The Final Problem was filmed mainly in Lloret de Mar on Spain’s Costa Brava. The production also used locations in Toledo and studio facilities in Tres Cantos, near Madrid.
Filming took place in spring 2025. Around 150 crew members worked on the Lloret de Mar shoot. The production used real Spanish locations along with studio sets to create the fictional hotel and its surroundings.
One important detail is that the story is set on a fictional islet near Mallorca, but the series was not filmed in the Balearic Islands. The filmmakers instead used locations along the Costa Brava and other parts of mainland Spain.
Filming for The Final Problem took place in spring 2025.
The production worked across several parts of Spain, with Lloret de Mar serving as one of the main filming bases. Additional filming took place in Toledo, Girona, and Tres Cantos near Madrid.
The filmmakers combined real locations with studio filming to create the fictional hotel and the isolated world seen in the series.
📍Jardins de Santa Clotilde, Lloret de Mar, Catalonia
The Jardins de Santa Clotilde in Lloret de Mar were one of the most important filming locations for The Final Problem. The gardens were used as the main exterior setting for the fictional hotel where much of the story takes place.
The gardens sit on a cliff above the Mediterranean Sea and Cala Boadella. Their grand stairways, sculptures, tall trees, and sea views give the series the isolated look needed for its mystery story.
The hotel shown in the series is not a real hotel that visitors can book. The production used the real gardens for the exterior scenes, while other parts of the hotel were created inside studio sets.
📍Cala de Sa Boadella, Lloret de Mar, Catalonia
Address: Cala Boadella, 17310 Lloret de Mar, Girona, Spain
Cala de Sa Boadella was another filming location used for The Final Problem. This small Mediterranean cove is located below the Santa Clotilde Gardens.
The rocky coastline and open sea helped create the remote setting seen in the series. The location also fits the story’s isolated island atmosphere, even though the actual filming took place on the Costa Brava.
📍Casa Roviralta, Lloret de Mar, Catalonia
Casa Roviralta was also used during the production of The Final Problem. The historic property is connected with the Santa Clotilde estate and is part of Lloret de Mar’s architectural heritage.
Using Casa Roviralta gave the production another real location in the same coastal area. It also helped add a classic Spanish setting to the series.
📍Castle of Sant Iscle, Vidreres, Girona
Address: 17411, Girona, Spain
The Castle of Sant Iscle was another location connected with the filming of The Final Problem. The castle is a ruined 12th-century medieval fortification located on a hill near Vidreres in Girona.
The historic ruins give the production a very different look from the Mediterranean gardens and beaches of Lloret de Mar. The castle dates back to the medieval period and was first recorded in 1194.
📍Toledo, Spain
The production also filmed in Toledo, one of Spain’s best-known historic cities.
Toledo is famous for its medieval streets, old buildings, and historic architecture. These features gave the series another visual style and allowed the filmmakers to expand the production beyond the Costa Brava locations.
📍Tres Cantos, Madrid, Spain
Some scenes from The Final Problem were filmed at Netflix’s production facilities in Tres Cantos, north of Madrid.
The studio location gave the production more control over indoor scenes. It was especially useful for scenes that needed controlled lighting, sets, and other production elements that could not easily be created at the outdoor filming locations.
